A guy sticks his head into a barber shop and asks, “How long before I can get a haircut?”

The Barber Bob looks around the shop and says, “About 2 hours.” The guy leaves.

A few days later the same guy sticks his head in the door and asks, “How long before I can get a haircut?”

The Barber Bob looks around at the shop full of customers and says, “About 3 hours.” The guy leaves.

A week later the same guy sticks his head in the shop and asks, “How long before I can get a haircut?”

The Barber Bob looks around the shop and says, “About an hour and half.”

The guy leaves. The Barber Bob looks over at a friend in the shop and says, “Hey,Harry , follow that guy and see where he goes. He keeps asking how long he has to wait for a haircut, but then doesn’t come back.”

A little while later, Harry comes back into the shop, laughing hysterically.
